Code: 

char* serialName = new char[8];
The serialName is shared and overwritten for all bodies/shapes. This is not OK because there is no copy made, so during btDynamicsWorld::serialize, all bodies will have the same name.

Try allocating a name for each body/shape dynamically and don't share the memory.

Thanks,

Code: 

//create a large enough buffer. There is no method to pre-calculate the buffer size yet.int maxSerializeBufferSize = 1024*1024*5; btDefaultSerializer*serializer = new btDefaultSerializer(maxSerializeBufferSize);dynamicsWorld->serialize(serializer); FILE* file = fopen("testFile.bullet","wb");fwrite(serializer->getBufferPointer(),serializer->getCurrentBufferSize(),1, file);fclose(file);

Note that while running most of the (unmodified) Bullet demos, you can press '=' key to serialize to a .bullet file, named "test.bullet". It will serialize all objects and constraints in the dynamics world. Some collision shapes are not supported yet (btHeightfieldTerrainShape for example).

Thanks,
Erwin
